Irelands most haunted castle.... Leap Castle is said to be haunted by a number of spectres, the most terrifying being a small hunched creature whose apparition is accompanied by a rotting stench of a decomposing corpse and the smell of sulphur. The O'Carrolls, princes of Ely, built it as their main stronghold in 1250 A.D. It was erected on a most commanding site facing the Great Pass through the Slieve Bloom Mountains to the province of Munster. It has a massive tower and walls nine feet thick. Gory murders are said to have taken place there - notably at a window high up in the tower. Visits to Leap Castle are by appointment with the other who can be reached at the contact details below .
